Title: Ion electrode measuring device
Inventor: GOTO TAKESHI
IPC: G01N27/416
Filed: 1991-05-24
Abstract: PURPOSE:To obtain an ion electrode measuring device without any leak current to an indicated electrode body regardless of insulation resistance of a sealed portion. CONSTITUTION:An ion electrode measuring device is provided with an indicated electrode 1, a comparison electrode 2, and a first amplifier 3 of a high input impedance which outputs a voltage which is logarithmically proportional to a differential voltage between the indicated electrode and the comparison electrode. A second amplifier 4 with a single gain and a high input impedance is placed between an electrode body 7 of the indicated electrode and an internal pole 6 of the indicated electrode. Since a potential of the internal pole 6 equals that of the electrode body 7 due to operation of the second amplifier 4, no leak current flows from the internal pole 6 to the electrode body 7.

IPC: H04B7/005
Filed: 1982-07-13
Abstract: PURPOSE:To improve the quality of line and to economize the system, by attaining the optimization of a level diagram as the entire communication system, in a satellite communication amplifying two waves with one repeater. CONSTITUTION:A voltage representing the S/N value of a transmission line of an opposite station passes through an upper and lower limit circuit 14, then it does not exceed a voltage corresponding to the S/N value of the upper and lower limit determined in advance. A voltage of the S/N value of a transmission line of an own station is compared with the voltage of the circuit 14 and the transmission power of the own station is limited so that the output is increased by DELTAV. If the level of a subcarrier is decreased abnormally, a switch 20 is selected to the position (2) with an output of a detector 19 and the control of a variable attenuator 9 is performed with a constant voltage Va. Thus, the level diagram is optimized regardless of either fine or rainy condition.
